Tax Advisory in Madrid: Your Fiscal Partner in the Spanish Capital

Tax advisory in Madrid operates within Spain's most active tax enforcement jurisdiction, where the AEAT's Special Delegation for Madrid and the Central Large Taxpayer Delegation (DCGC — covering entities with turnover above EUR 100 million) conduct technically intensive audit proceedings for companies and individuals domiciled in the capital. The Comunidad de Madrid (CAM) offers some of the most favourable personal tax conditions in Spain: a 100% Wealth Tax (IP) exemption for residents, a 99% Inheritance and Gift Tax (ISD) reduction on transfers between direct descendants, and competitive regional IRPF rates — advantages that require careful residency and asset structuring to capture correctly given the national Solidarity Tax on Large Fortunes (ITSGF, applicable above EUR 3 million).

Why tax advisory in Madrid requires specific sector expertise

Madrid is not an ordinary tax jurisdiction. The AEAT Special Delegation for Madrid and, for the most significant taxpayers, the Central Large Taxpayer Delegation, conduct audit proceedings with a technical intensity and sophistication unmatched elsewhere in the country. If your company is headquartered in Madrid, operates in the capital markets, belongs to a multinational group, or holds a significant wealth portfolio, you need tax advisers with deep expertise in this environment.

Tax planning in Madrid also demands knowledge of the Comunidad de Madrid’s specific incentives: the 100% Wealth Tax exemption — partially offset by the State’s Solidarity Tax on Large Fortunes, though partially recoverable through residency planning — and the 99% ISD reductions between direct descendants, which make Madrid one of Spain’s most tax-efficient regions for personal and succession planning.

Our Madrid tax team: full-service coverage from planning to defence

Our team at the Madrid office combines large-account specialists and international group experts with professionals dedicated to personal wealth planning and mid-market business advisory. This combination means we can serve a US group’s Spanish subsidiary with complex transfer pricing needs with the same depth as a Madrid entrepreneur seeking to optimise their company’s remuneration policy and succession planning.

For corporate transactions, we work alongside our mergers and acquisitions and commercial law teams to ensure every deal is designed with tax efficiency built in from the outset. A well-designed acquisition structure can mean several percentage points of difference in the final return on investment.

Comunidad de Madrid fiscal incentives you cannot afford to miss

The CAM offers some of the most significant personal tax advantages in Spain’s tax system:

• Wealth Tax: 100% exemption for Comunidad de Madrid residents (the Solidarity Tax on Large Fortunes limits this advantage for very large portfolios, but residency planning remains decisive).
• Inheritance and Gift Tax: 99% reduction on transfers between parents and children, making Madrid the country’s most favourable region for succession planning.
• Regional IRPF deductions: the CAM applies additional deductions on the regional IRPF tranche for investments in startups, main residence rental, large families, and other items.

What our Madrid tax advisory service includes

From our Madrid office we provide the full tax advisory service: monthly and annual tax compliance (IS, VAT, IRPF, IP, ISD), strategic planning, audit defence, transfer pricing for international groups, M&A tax advisory, corporate restructurings, and personal and succession wealth planning.

For companies with international tax exposure — subsidiaries abroad, foreign shareholders, cross-border royalties — our team has experience applying double taxation treaties, the parent-subsidiary directive, and OECD/BEPS standards.

Madrid as Spain’s principal tax centre

The Comunidad de Madrid accounts for more than 20% of Spain’s total GDP, hosts the headquarters of more than 70% of IBEX-35 listed companies, and concentrates the highest density of internationally active businesses in the Iberian Peninsula. This economic weight translates directly into tax complexity: Madrid-based entities face larger-scale AEAT audit activity, more sophisticated transfer pricing scrutiny, and greater regulatory pressure than companies operating elsewhere in Spain.

For international tax matters, Madrid is particularly significant. Double taxation treaty applications, Directive on Administrative Cooperation (DAC6) reporting obligations, and Base Erosion and Profit Shifting (BEPS) compliance for Spanish operations of multinational groups are all handled through Madrid-based advisers in most cases. Our team has direct experience advising US, UK, French, and German group subsidiaries on these requirements.

Corporate tax planning specific to Madrid-based entities

Corporate tax planning in Madrid demands familiarity with several regime-specific features that do not apply in the same way elsewhere:

• Consolidated tax group regime: Madrid companies belonging to multinational groups frequently elect to form or integrate into a Spanish consolidated tax group, which allows loss offsetting and intra-group transfers at book value. Structuring this correctly requires detailed analysis of the shareholding chain and intercompany transactions.
• Patent box and IP regimes: The Spanish patent box (Article 23 LIS) allows a 60% reduction on income derived from qualifying intangible assets. Madrid-based R&D operations or IP holding structures frequently have access to this benefit if properly documented.
• Startup Law incentives: Under the 2023 Startup Law (Ley 28/2022), qualifying newly incorporated entities pay corporate tax at a reduced 15% rate for the first four profitable years. Madrid is Spain’s principal startup ecosystem, and our team advises founders on qualifying for and maintaining this benefit.
• Employee stock options: The Startup Law also improved the fiscal treatment of employee equity awards. For Madrid-based technology companies, this has become a critical retention and incentive tool with specific compliance requirements.

Transfer pricing in Madrid: AEAT’s primary scrutiny area

Transfer pricing remains the most active area of AEAT inspection activity for Madrid-based multinational groups. The Central Large Taxpayer Delegation has dedicated transfer pricing specialists and increasingly applies econometric and functional analyses that require equivalently rigorous documentation from taxpayers.

Our Madrid transfer pricing team prepares master files (MF), local files (LF), and Country-by-Country Reports (CbCR) to OECD standards. We also advise on Advance Pricing Agreements (APAs) with the AEAT where predictability is essential, and defend existing positions during audit proceedings.

Wealth and succession planning in the Comunidad de Madrid

The CAM’s 100% Wealth Tax (IP) exemption and 99% Inheritance and Gift Tax (ISD) reductions are powerful planning tools — but they require careful implementation. For Madrid residents, the key planning elements include:

• Residency confirmation: establishing and maintaining fiscal residency in the CAM is a prerequisite for the exemptions. For high-net-worth individuals with multiple properties or frequent travel, this requires proper documentation.
• Solidarity Tax interaction: the national Solidarity Tax on Large Fortunes (ITSGF) applies to net wealth above EUR 3 million and partially limits the CAM IP exemption. Residency planning and asset structuring can reduce ITSGF exposure significantly.
• ISD planning for business owners: transferring family business assets to the next generation in a tax-efficient manner requires combining the CAM ISD reductions with the business assets exemption (empresa familiar), which has strict operational requirements.

Our succession planning and family office teams work alongside our Madrid tax specialists on these mandates.

Integration with the Madrid legal ecosystem

Tax planning cannot be separated from legal structure. Our Madrid team works in close coordination with our commercial law and M&A practices to ensure that corporate reorganisations, share deals, and holding structures are simultaneously legally sound and fiscally optimal. In complex transactions involving real estate, intellectual property, or regulated activities, multi-disciplinary coordination is not optional — it is the only way to deliver genuinely sound advice.

Regulatory framework: AEAT enforcement in Madrid

Madrid taxpayers interact with two distinct AEAT enforcement units, each with its own audit profile and procedural characteristics:

AEAT Special Delegation for Madrid (Delegación Especial de Madrid): the territorial AEAT office for companies and individuals domiciled in the Comunidad de Madrid. Its inspection unit covers companies and individuals outside the DCGC perimeter. It is the most active AEAT territorial delegation in Spain by inspection volume, with dedicated units for large-scale IRPF audits, real estate transactions, and VAT carousel fraud.

Central Large Taxpayer Delegation (DCGC — Delegación Central de Grandes Contribuyentes): the national-level AEAT unit responsible for Spain’s most significant taxpayers — companies with annual turnover above EUR 100 million, financial institutions, insurance companies, and companies with assets above EUR 150 million. Its inspection proceedings are technically intensive, typically covering multiple tax periods simultaneously and focusing on transfer pricing, intra-group financing, and hybrid structures. The DCGC issues binding tax criteria that influence how lower-level AEAT units subsequently audit similar issues.

General Tax Act (LGT, Law 58/2003): the procedural backbone of all Spanish tax proceedings. It defines inspection timelines (standard 18-month limit, extendable to 27 months for complex cases), taxpayer rights during audit, penalty reduction incentives (25–50% for prompt payment and non-appeal), and the appeals hierarchy: Tribunal Económico-Administrativo Regional (TEAR) → Tribunal Económico-Administrativo Central (TEAC) → Audiencia Nacional or Tribunal Supremo.

LIRPF (Law 35/2006), LIS (Law 27/2014), and LITPAJD (RDL 1/1993): the three primary substantive tax laws applicable to most Madrid advisory mandates. The LIS is particularly relevant for corporate group structures (consolidated tax groups, Articles 55–75) and the special tax neutrality regime for restructurings (Articles 76–89).

Real Decreto 1065/2007 (RGAT): the General Tax Regulation governing inspection procedures, including the rules on mandatory accounting disclosure, electronic audit notification, and the electronic audit notification system (LCPJ).

Sectors with specific Madrid tax issues

Technology and startup ecosystem: Madrid is Spain’s principal startup hub. The 2023 Startup Law (Ley 28/2022) introduced a 15% IS rate for newly incorporated qualifying entities for the first four profitable years. Eligibility requires: innovation-driven activity, annual revenues below EUR 10 million, and a maximum company age of five years (seven for biotech). Employee equity awards benefit from deferred taxation: up to EUR 50,000 per year (raised from EUR 12,000) deferred until the earlier of exit, transfer, or admission to trading on a regulated market.

Financial services: Spain’s major banks (BBVA, Banco Santander, Banco Sabadell), insurers, and asset managers are headquartered in Madrid and domiciled within DCGC scope. Financial sector entities face specific taxation under the Financial Sector Tax (Law 5/2022 — Gravamen Extraordinario a Entidades de Crédito), with a rate of 4.8% on net interest income and commissions above EUR 800 million. Advisory on this specific measure and its interaction with the standard IS is a recurring mandate.

Real estate and SOCIMIs: Spanish Real Estate Investment Trusts (SOCIMIs) are subject to a 0% IS rate on qualifying rental income, provided 80% of profits are distributed as dividends. Shareholders — both resident and non-resident — are taxed on distributions at their applicable rate. Madrid’s real estate market generates significant IP (Impuesto sobre el Patrimonio) and ISD advisory requirements for high-net-worth investors and family offices. The ITPAJD applies to real estate acquisitions at the AJD (stamp duty) rate (0.75% in the Comunidad de Madrid, below the national average).

Multinational groups with Madrid headquarters: Spanish subsidiaries of US, UK, French, and German multinational groups frequently face simultaneous transfer pricing scrutiny, Pillar Two (Global Minimum Tax — Council Directive 2022/2523, transposed into Spanish law) compliance obligations for groups with revenues above EUR 750 million, and country-by-country reporting (CbCR) requirements under Law 27/2014 Article 13 bis.

Family businesses (empresa familiar): the business assets exemption (exemption from Wealth Tax under Article 4.Ocho.Dos LIP for qualifying interests in family businesses) is the cornerstone of family wealth planning in Madrid. It requires that the interest represents more than 5% for the taxpayer individually or 20% for the family group, that the principal economic activity is not the management of movable assets, and that the taxpayer exercises effective management functions receiving remuneration representing more than 50% of their total net labour and professional income. Maintaining these conditions and combining them with the ISD reductions is a permanent advisory mandate for business-owning families.

Company size segmentation

Autónomos and small businesses (turnover below EUR 1M): IRPF income tax optimisation — choosing between direct estimation (estimación directa) and objective estimation (módulos), managing quarterly 111/130/303 filings, and optimising deductible expenses and social security contributions. The Comunidad de Madrid IRPF regional deductions (investment in new companies, rental income from main residence, etc.) are frequently missed by non-specialist advisers.

SMEs (EUR 1M–EUR 50M): full IS compliance including R&D&I deductions (Articles 35–36 LIS), corporate group consolidation analysis, transfer pricing for intra-group transactions above EUR 250,000 per counterparty, and AEAT Madrid inspection defence. The Startup Law incentives are accessible to qualifying companies in this range.

Large Spanish companies (EUR 50M–EUR 100M): approaching or within the Special Delegation perimeter. Transfer pricing master file and local file preparation (Articles 16–18 LIS; RD 1793/2008), monthly VAT SII (Suministro Inmediato de Información) compliance, and AEAT audit management. CNMV reporting obligations where shares are listed.

Multinational groups above EUR 100M: DCGC perimeter. Pillar Two GloBE minimum tax computation and domestic top-up tax analysis, CbCR filing, full transfer pricing documentation, and coordinated defence strategy across multiple tax periods. Madrid acts as the coordination point for Spanish operations of international groups.

Worked example: Madrid holding group restructuring and Wealth Tax optimisation

Background: a Madrid-based entrepreneur held a group of companies (three operating subsidiaries and a holding) in his own name, with an estimated equity value of EUR 18M across the group. He also held a EUR 3.5M residential property portfolio in Madrid and EUR 1.2M in quoted shares. Total net wealth: approximately EUR 22.7M. Annual Wealth Tax (IP/ITSGF) exposure before planning: approximately EUR 380,000.

Analysis: the operating company interests qualified for the business assets exemption (Article 4.Ocho.Dos LIP) because he exercised management functions and received qualifying remuneration, but the property portfolio and quoted shares were fully exposed to IP. The national Solidarity Tax on Large Fortunes (ITSGF, Law 38/2022) applied to net wealth above EUR 3M at progressive rates (1.7%/2.1%/3.5%), partially offsetting the CAM IP exemption.

Measures implemented:

1. Holding company restructuring: the three operating subsidiaries were brought under a properly structured holding with formal board, documented management fees, and qualifying activity — strengthening the empresa familiar exemption position.
2. Property portfolio review: two of the residential properties were reclassified as development assets via a property company vehicle, deferring exposure from IP to the vehicle’s balance sheet and outside the ITSGF perimeter for non-resident shareholders.
3. Investment portfolio restructuring: EUR 800K of quoted shares were transferred to a Luxembourg SICAV-SIF, reducing the IP base by EUR 800K without triggering capital gains (tax-deferred reorganisation under ATAD equivalents).
4. Remuneration structure: annual remuneration from the holding was formally set at EUR 195,000 — exceeding 50% of total professional income — to satisfy the empresa familiar exemption condition each year.

Outcome: ITSGF and IP liability reduced from approximately EUR 380,000/yr to approximately EUR 52,000/yr (solely on assets outside the planning perimeter), a saving of EUR 328,000 annually. Documentation prepared and submitted to AEAT with a binding consultation (consulta vinculante) request to obtain legal certainty.

Five common mistakes in Madrid tax planning

1. Assuming the Comunidad de Madrid IP exemption eliminates all Wealth Tax. The national ITSGF (Law 38/2022) applies on top of, and partially neutralises, the CAM exemption for portfolios above EUR 3M. Planning must account for both levies simultaneously and analyse the interaction with the empresa familiar exemption.

2. Undocumented related-party transactions. The AEAT DCGC routinely requests transfer pricing documentation as the first step in large taxpayer audits. Companies without a contemporary master file and local file (prepared before the tax period closes) face automatic penalty exposure under Article 18.13 LIS — EUR 1,500 per data item, EUR 15,000 per data set, and a 15% surcharge on the adjustment amount.

3. Missed R&D&I deductions. LIS Articles 35 and 36 allow deductions of 25% (R&D) and 12% (IT) on qualifying expenditure, with a further 42% deduction for personnel costs classified as researchers. Madrid technology and industrial companies consistently under-claim these deductions because the qualifying-activity analysis is not applied rigorously. AEAT’s subsequent challenge to inflated deductions is equally costly. Correct documentation is essential.

4. Failing to file the Solidarity Tax on Large Fortunes separately. ITSGF (Modelo 718) is a separate filing obligation from IP (Modelo 714), with its own deadlines. Madrid residents who file IP and believe they have zero liability (due to the CAM exemption) sometimes fail to file ITSGF where their net wealth exceeds EUR 3M. Penalty: EUR 150 per data item plus automatic surcharges.

5. Ignoring Beckham Law application deadlines for incoming executives. The special tax regime for inbound assignees must be elected within six months of Social Security registration. Executives who register late — or whose HR departments fail to flag the option — lose the regime permanently. The cost of missing this election is six years of worldwide taxation at progressive rates (potentially 47%) rather than Spanish-source income only at 24%.

How we work: Madrid tax advisory process

Our Madrid tax team operates through an integrated coverage model: each client is assigned a principal adviser (a senior manager or partner with the relevant expertise) supported by specialists in the areas their tax profile requires — transfer pricing, M&A, personal wealth, AEAT audit defence, or international tax.

On-boarding (month 1): tax diagnostic reviewing the last three years’ IS, IRPF, IP, and ISD filings; identification of unclaimed deductions, underdocumented positions, and AEAT audit risk; preliminary mapping of restructuring opportunities.

Annual cycle: monthly or quarterly IS/VAT/IRPF compliance, SII filing management (where applicable), annual tax planning memo updating the strategy in light of legislative changes (published each November after the State Budget and LGT reform cycles), and renewal of transfer pricing documentation.

Reactive: AEAT audit management from initial notification through TEAC appeal if required; binding consultation (consulta vinculante) requests before implementing significant structural changes; M&A tax support on transactions.

Initial diagnostic meetings are offered at no charge and without commitment. Ongoing advisory is priced under a fixed monthly retainer covering compliance and standard advisory, with agreed project fees for audit defence and M&A mandates.
